$SPDR S&P 500 ETF (SPY.US)$  how far down can it go ?

$NVIDIA (NVDA.US)$ for those who are clueless when to enter.. for me, apart from nvdia TA, im looking closely at sp500 (september typicall falls between 7% to as much as 15%.) since nvida and all megacaps are showing bearish signals like i mentioned last week. just plan your trades, always enter at support levels & buy in 3 to 4 seperate tranches. no need to rush and catch the falling knife. there can be some rebound, but like i said. it will make its way down there. just be patient.
