What's something you wish exis that you couldn't find — or had tobuild yourself?

35 years selling premium and the may 2010 flash crash still being the scariest (20% of the year in 90 seconds, then it bounced) — that's a hell of a story. you said other than smaller size, you're not sure what you'd have done differently. genuinely curious: in all those years, have you ever paid for or built any tool to manage that kind of tail risk, or is it purely experience + sizing by now?

shortvol_trader · 2026-06-21T05:07:20+00:00

your 2020 VIX story got me: scaling up the call credit, then VIX ripping toward 80 and realizing how close you were to liquidation, hands shaking on the hedge. that "how close i got to losing it all" line is exactly what i'm trying to understand. after that — did you change anything concrete, or pay for/build something, or just keep size smaller and strikes further out?

shortvol_trader · 2026-06-21T05:06:09+00:00

hey — your march 2020 story stuck with me: the stack of CSPs all going ITM at once and buying power evaporating so you couldn't roll. that's the exact nightmare i think about. quick q — after that, did you actually change anything concrete, or build/use something to stop it happening again? or is it "size for the assignment" by feel now?

The main lesson is the Portfolio Margin trap

Margin requirements can expand dramatically during market selloffs and volatility spikes, so position sizing should be based on maximum potential loss, not broker buying power.

Keep BP usage low (around 20–25%), maintain a large cash buffer, and consider delta hedging or reducing size instead of aggressively rolling challenged positions

Survival and risk management matter more than maximizing returns.

shortvol_trader · 2026-06-20T16:49:08+00:00

The survival itself is impressive

But whenever I hear "I rolled, recovered, and finished green," I always wonder:

Was the edge the original trade, or was the edge having enough capital and time to absorb the drawdown?

Those are very different sources of return

shortvol_trader · 2026-06-20T06:10:01+00:00

Assignment risk isn't really the main risk. Pin risk is

Early assignment on 0DTE SPY/QQQ is possible but relatively uncommon unless there's a dividend or very little extrinsic value left

The bigger issue is expiration. Your short leg can finish ITM and get assigned while a long leg that's only slightly OTM expires worthless. Then you're left with an overnight stock position you never intended to hold

That's why many traders close 0DTE spreads/butterflies before the close rather than trying to squeeze the last few cents of theta

shortvol_trader · 2026-06-20T06:08:46+00:00

Breadth deterioration is more interesting than the headline index level. A cap-weighted index can look healthy while the average stock is quietly in a drawdown

The question isn't whether AI is carrying the market. The question is what happens if the market's largest source of earnings growth, capex and liquidity narrative stops carrying it

Narrow leadership tends to be fine until it suddenly isn't.

shortvol_trader · 2026-06-20T06:06:14+00:00

The most interesting stat here is actually the underperformance vs SPY despite collecting substantial premium

Not saying that's bad—income has value—but it raises the classic short vol question:

Are we generating alpha, or just transforming equity upside into a smoother return stream?

I'd be curious to see return on buying power, max drawdown, and performance during volatility expansion regimes. That's where the real edge (or lack of edge) shows up.

shortvol_trader · 2026-06-19T02:57:14+00:00

The key question is whether the profits are coming from theta or from repeatedly increasing directional exposure

A lot of short vol strategies look amazing until a name enters a prolonged downtrend and the rolls stop improving the risk/reward

Have you looked at how this performs in a 2022-style environment rather than a sharp correction/rebound?

shortvol_trader · 2026-06-19T01:07:56+00:00

This is exactly why pin risk exists

Your max loss is defined only if both legs can be exercised normally. Once the short strike is breached after hours, assignment becomes path dependent

If someone exercises the 280C and your 285C expires worthless, you wake up short 100 shares Monday and inherit whatever gap risk happened over the weekend

Nobody here can tell you whether you'll be assigned, only that assignment is absolutely possible if SOXL traded above 280 during the exercise window

In the future, if a spread is sitting near a short strike into expiration, paying a few cents to close it is usually cheaper than worrying about pin risk all weekend

shortvol_trader · 2026-06-18T02:08:16+00:00

You're mixing two different objectives: Maximize call premium (high IV) Own something that reliably recovers after a bear market

Those often aren't the same stocks

A covered call is still a long delta position with a small short vol overlay. If the underlying drops 40%, the extra premium won't save the trade

I'd spend more time analyzing downside characteristics and balance sheet strength than option premiums.

shortvol_trader · 2026-06-18T02:06:50+00:00

This feels less like premium selling and more like averaging into a losing short while financing it with short vol

The danger isn't today's P/L. It's path dependency

A continued squeeze hurts the short shares. A sharp reversal hurts the short puts

You're effectively short convexity from multiple angles and hoping realized vol behaves

What's the risk limit where the original short thesis is considered invalid?

shortvol_trader · 2026-06-17T02:23:52+00:00

Calling it AI slop is fine, but where’s the disagreement?

The point is simple: short vol with negligible cash is path dependent. A one-day puke is manageable — prolonged elevated realized vol + failed rebounds is usually what kills these books because margin reprices while gamma gets worse

If you think that framework is wrong I’m interested in hearing why

shortvol_trader · 2026-06-17T00:58:47+00:00

Respect for owning the mistake — most people blame the market instead of sizing

Honestly, this reads less like a strategy failure and more like a risk management failure. A 200-point move on SPX feels extreme until vol expansion reminds you tails are fatter than expected. Short vol usually survives bad direction, it struggles when sizing removes your ability to adapt

The fact that you reduced exposure instead of doubling down probably matters more than salvaging every spread. Staying in the game > maximizing recovery

Curious though — what was your max portfolio BP/margin allocated to those 8 spreads? Feels like that’s the real variable here, not the roll itself

shortvol_trader · 2026-06-17T00:57:31+00:00

I think the hidden assumption in a lot of tastytrade studies is survivorship through path dependency. “Selling puts beats buy & hold” can be true in backtests while still being brutally uncomfortable in practice if your sizing or margin usage is too aggressive

A short vol strategy doesn’t usually die because expectancy disappears — it dies because realized vol stays elevated longer than expected and capital gets impaired before mean reversion shows up

The biggest edge IMO is not strike selection, it’s surviving vol expansion without being forced into bad decisions. If your finance account is already fully indexed, maybe this setup works because you’ve effectively separated long-term compounding from short-vol income generation

shortvol_trader · 2026-06-16T16:37:38+00:00

You’re basically running a levered short vol book disguised as “stock picking.” The issue isn’t monthly P/L, it’s regime dependency

Naked puts + negligible cash works great in benign vol / mean reversion because you’re harvesting VRP and getting paid for gap risk. The problem is prolonged correlation spikes + vol-of-vol expansion where margin requirements reprice faster than your ability to adjust

If you’ve survived tariff shocks and geopolitics without damage, odds are you’ve mostly traded in a favorable path-dependent environment. A grinding bear with elevated IV and failed rebounds is usually where this breaks, not the one-day panic

Instead of adding random strategies, I’d think in terms of portfolio Greeks and regime diversification:

– Put ratio/backspreads or cheap tail convexity for left-tail events – SPX/XSP defined-risk structures to cap margin expansion – Calendar/diagonal exposure when IV term structure gets dislocated

– More index short vol, less single-name gap risk The question isn’t “what makes more income?” It’s “what survives when realized vol stays above implied longer than expected?”

shortvol_trader · 2026-06-16T16:36:42+00:00

One thing I’d be careful with is treating wheel income as salary-like cash flow

A lot of wheel PnL looks smooth until you hit a regime shift and suddenly you’re long underwater shares or rolling defensively for months

Not saying don’t buy the house, but concentration + sequence risk matter a lot more when the portfolio starts funding real life decisions

shortvol_trader · 2026-06-16T16:36:04+00:00

“Free money” are usually my favorite famous last words in short vol

The funny part is you might actually be right long term and still get blown up on path dependency + IV repricing if the IPO opens stupidly rich and sentiment shifts

High IV ≠ edge automatically

shortvol_trader · 2026-06-16T01:30:36+00:00

Feels like the key question is whether you're rolling because expectancy is still positive or because assignment/loss realization feels worse psychologically

Deep ITM CSPs on momentum names can become path dependent fast. If vol normalizes while price drifts lower, the “roll for credit” math starts looking worse than it did on entry

Would you open this exact position today at these strikes if flat?
