Not financial advice, but I'm spreading some fun money to some low float small caps that have high CTB, utilization, and zero option chains. These types of stocks are explosive and MMs have less liquidity without the option chain, so even moderate buying pressure can make these stocks run and run fast. These things can run 15%-20% daily in any direction. On most swings, I allow myself 5-10% downside potential before exiting, on these plays however, I'm willing to go to 40%, but to counter that, I also only put half the normal investment in, so my actual dollar loss is about the same.
