With more and more retail traders piling in, and S&P climbing higher and higher, when will SPY split? Not all brokerages support partial shares, and it's hard for many people to muster up the cash to even buy one share. On the flip side, SPY being high means there's a lot of leftover cash that can't be effectively moved in. Additionally, options on SPY are getting close to a notional $40K amount, which is debilitatingly high. Regular people can't afford to execute the option at expiration. It seems like if CBOE and brokers want to keep charging high fees per contract, they would prefer people to trade smaller and more frequently. So, when will SPY split?
