So assuming you had $100 and got a 3% return everyday on your portfolio (excluding the transaction/brokerage fees), if you did that 100 times in a row for each possible business day (so guessing maybe about close to half a year) you would have $1921.86 at the end of it ...which is more than 19 times the original amount. I know its crazy (and not feasible in real life) but that just boggles my mind.
. No, you can't "risk 5% of your capital while parking 95% in T-Bills. You can take all kinds of aggressive risks with 5%... risks you wouldn't take with "all of it".)
