Common indicators? For sentiment indicators I've seen volatility (VIX) and put-call ratio discussed. A bit of googling reveals the CFTC COT (Commitment Of Traders) index which I hadn't heard of before [1]. What other short and long horizon indicators are good to consider? A nice one to have right now would be some kindof world debt crisis indicator! Or we should just all invest in Russia (one of the lowest debt-to-GDP ratios) [2].
