Quote from DemTraydor:
Based on my own experience, I'd give Don the benefit of the doubt on this.
I trade a variation of the opening strategy at another firm and while I average less than the numbers Don is quoting here, I can see the numbers he gave being achievable.
The hedge fund argument makes sense, but also keep in mind that the scale of a prop firm's capital being used for this type of strategy is more realistic.
Each trader is given about 500k of buying power, some less and some more presumably, to work with in this case. Assuming there are maybe 100 traders at Bright who run this strategy (not all do) on roughly the same basket of stocks (and I say roughly because in my experience, most traders choose a different enough basket that each can avoid taking the others' liquidity even on less liquid stocks, but I can't speak for Bright on this part), that's about 50 mil of buying power in total.
A hedge fund with a 50 mil NAV is among the extremely small funds. (The minimum to be registrable on a federal level with the SEC after Dodd Frank is 150 mil if I remember correctly, just off the top of my head.)
I'd suspect (haven't actually looked into this part) that most of the ones struggling to make 30% annually are more than ten times bigger and would probably single-handedly throw off the opening imbalance of each stock in the basket if they allocated even 1% of their capital to a strategy like this. (I guess in theory they could do a very very large basket with even smaller allocations each, but I'm not sure if the payoff for something like that would work for a medium or large fund's scale. At least the way I learned to choose stocks for this strategy makes it hard for that to work, but I know Don's is a bit different.)
Of course, this is all just off the top of my head. I've never personally dealt with Bright so I can't say one way or the other how accurate a picture Don's painting here of his traders or their success and consistency.
