Pretty regularly I see charts like these where something happens and the gap is filled much later on. What could cause the gap to fill is excitement about Novavax in coming weeks. For others looking on, I make no predictions. This is all speculative.
Novavax is dirt cheap at the moment, so it seems useful to take a controlled affordable loss going long (at this time). If the market moves much further north, stop losses will become heftier for those coming in late. Not a good idea to chase this market north. It's about getting in at the right time. So - I think Meszaros has probably got in at the right time i.e. smaller losses with potential big gains - and no need to chase.

Based on your reply I assume your on the side of changing your money management strategy dependent on your account size? Regardless of whether you advise this, I still don't understand your decision to not include your stop losses in your analysis', all your publishings follow the warning you wrote (below your profile picture) "The analyzes on this site are private opinions and not investment advice." So why not include stop losses? Providing a target price in effect is half the piece of the pie which you always do...just curious
Also, there has been a really strong pull back this morning since Friday last week. Is this a bad sign or do you expect more bullish move to the upside?
