Quote from Cutten:
1370ish was modest resistance - it was the prior lows from August and earlier Jan. On Friday we gapped up to that level and immediately sold off. I agree it's not heavy resistance but trading off that level would have been very useful on last Friday after the initial 115 point S&P rally.
Same with 1420-30 - the market stalled there earlier this month, so it's probably a good place to lighten up on longs.
In any case, levels on the S&P or any other index are always a bit more vague than for individual stocks or markets like commodities, forex etc. The reason is that an index value is dependent purely on the constituent stocks. So 1375 last month may have seen most stocks hit their individual support levels. But 1375 recently may have seen some stocks above resistance, and some below resistance. The index value is the same, but the technical picture for the 500 stocks in the index could be radically different.
This is why I'm always a bit cautious with using technicals on indices. With the VIX out there, there's less need to rely on precise levels anyway.
