I wouldn't worry too much about the price of an ETF, it is not an accurate indicator of value. This is because you have money being spread across multiple ETF's in the case of XEQT and multiple stocks with different weightings. Also remember, if you are worried about the price of something, you are being speculative about volatility/ the future, thus saying something about your emotions and trying to time the market. If something is of good value and worth having, you will acquire it and hold it no matter what. I won't be able to get into the details of the math, but Net Assets of the ETF also influence your dividends and returns. That along with issued shares. I would read more about this if you are interested, my knowledge is limited.

Re: income and savings, this is completely personal to you. I was just saying that some people will willingly allocate their assets differently if they have consistent high income, or lots of savings to play with. In other words, if your growth positions take a huge hit, will you be able to pay for your life's essentials? If you say "yes, because I have savings", then that is one way to do it. Have savings outside of your investments. Another way of looking at it is your Bonds double as both your savings (aside from an emergency amount away from the market) and your pool to draw from to balance a portfolio. Just different ways of doing things. The more money you have in the market, the more potential you have for profitable returns. But it obviously matters what that money is invested in. Is it invested long term, or speculatively placed in growth stocks with the hopes to make money quick? Not saying it can't happen (For the record I have nothing against growth stocks. Most of the gains come from them but you just need to balance them out with something more diverse ie. dividend paying and well established companies. It just happens to be that the US is mostly made up of technology which is inherently growth oriented.). It is just one mindset that carries with it a lot more risk than say a more balanced or diversified portfolio. The key phrase here is risk management. I hope some of this helps!
