Equities Could Be Overextended But Further Upside Lies Ahead

 | Mar 05, 2016 08:22PM ET

Summary: Equities rose 3% for their third weekly gain in a row, led by small caps and further gains in oil. The SPDR S&P 500 ETF (NYSE:SPY) has now rallied 10%, back to a level that was major support throughout most of 2015. It would be easy to say that the rally ends here, but strong breadth, persistent investor pessimism and strength in other asset classes suggest that further upside ultimately lies ahead. That said, by the end of the week, the advance showed several signs of being overextended; weakness early next week would be normal. In fact, if equities continue with an uncorrected rally, those gains are likely to be given back in the weeks ahead.

Equities continued to rally for the third week in a row. For the week, SPY gained 2.7% and NDX gained 2.2%. RUT again led to the upside, gaining 4.3%, making this a broad-based rally.

Safe havens - Treasuries and gold - which had been in high demand during the sell off in equities, were split: Treasuries lost 1% for its third weekly loss in a row, while gold rose 3% after falling the prior two weeks.

Oil gained another 10% this week. It's leading to the upside.

It's easy to forget, but the correlation between asset classes remains very high, with the common denominator being the price of oil. Oil bottomed on February 11, the exact same day equities, high-yield bonds and treasury yields all bottomed. Until Thursday, that day also marked the high point for gold.

The implication is that for the rally in equities to continue, the price of oil has to also rise, or at least stabilize. We'll review other indictors, but it's likely these will make little difference if oil starts to fall. It's the single biggest wild card facing all of these markets in the weeks ahead (enlarge any chart by clicking on it).
