What happened that day?

17 June 2002 — the S&P 500 rose 2.87% to close at 1,036.17. No single cause can be pinned to the day
The previous sessions had been a steady slide. A large one-day gain from a low level happened several times that year
What the market was watching in 2002 was not earnings but whether the numbers could be trusted. Accounting frauds were surfacing one after another
So bounces came not from good news but on days with no new bad news
The next session barely moved and the slide resumed after it. This bounce did not last two days
From the mid-March high to the 9 October low the index fell 33.63%
9 October was the bottom of the whole dot-com collapse
