Should market strategies be kept secret?

If you found a way to beat the market, such as every wednesday buying into TGT at 10am and selling at 2pm would make you profit every single time, would you share that information with others? Once other people start doing it, wouldn't it change the outcome? Or are some strategies able to withstand such a huge influx? I'm curious!
