"put in a sell orders at $5.00"
Theory is sound but not practical to implement.
You would need the vast majority of investors to do so with most of their holds, and then it would still be not enough per following:

Often the shorters are holders of cheap shares from PPs and use them as a buffer against sudden upward moves in sp with news. They will short to the extent of the volume they have in cheap shares for safe cover. Note how our sp stopped sliding near the effective price obtained from last placement ( $1.80 + tax breaks = $1.20 or so).
If great news comes, if they limit their shorting volume to shares on hand they do not need to cover at the new high price. If anything they will sell some of their hold on the price spike.

It is a free licence to practice.
