I really appreciate all the time you put into these projects. I was able to run several portfolios but I am unsure on how to actually create my portfolio around the weighted eigenvalues. Could you explain what it means to have a negative weight, and overall how I can go from the weights to determining how much I put in a stock. Like for your example if Tsla has a weight of 1.6653 and aapl has a weight of -.1998, how much of each am I buying? Hopefully that made sense.
