After increasing volatility stirred up some investor anxiety in the week ended May 22, most indicators suggest that bullishness is back on the rise. As has been duly noted in recent months, the shift in sentiment is positive, as it comes after a stock market crash in 2008 and, only once confidence is restored, can the market make a sustainable move higher. That trend appears to be intact and now some sentiment indicators are reaching levels not seen in more than a year.
Investors Intelligence reports that bullish sentiment increased a bit and bearishness fell last week. The survey now reads 40.9 percent bullish and 28.4 percent bearish, which compared to 40.7 bullish and 29.1 percent bearish the week before. According to the Investors Intelligence poll, bearishness is at its lowest levels since May 16, 2008!
Other indicators also point to rising levels of bullishness. For example, the ISE Sentiment Index, which tracks daily call volume divided by daily put volume (X100) on the International Securities Exchange [ISE] saw a spike Friday. ISEE finished the day at a two-month high of 175, suggesting that put buying was running 57 percent of call purchases on the ISE, the largest exchange for equity puts and calls.

From a contrarian view of the markets, high levels of bullishness often urge caution. If everyone is piling on one side of the ship: Get on the other!
However, in the post-crash world, it might be dangerous to assume the market is overbought. In fact, the increasing levels of optimism are feeding money into the equity market. AMG data reports that $4.6 billion flowed into stock funds in April. $2.9 billion moved into equity funds the past two weeks. While the flows aren’t massive, they stand in stark contrast to the fourth quarter of 2008 and the first quarter 2009 when funds were being hit with massive redemptions!
In conclusion, the equity market has shown impressive resilience over the past few months and the trend can feed on itself, as increasing levels of optimism motivates more money to move into the equity market. In this environment, it still makes a lot of sense to look for opportunities to trade the market in both directions by tracking the options order flow and identify those stocks/industry groups/sectors that are at risk of another wave of selling for bearish opportunities. Focus bullish trades on those groups showing upside momentum and bullish order flow.
