Cowen analyst Oliver Chen believes the after-market strength in Restoration Hardware shares following the company's Q2 earnings beat is not justified. The analyst said the beat was driven by the low-quality pull forward of Q3 demand, since comps were running negative and deteriorating in the second half. He believes there is still too much uncertainty in sales inflection, execution issues, and negative free cash flow for investors to get involved. Chen maintained his Market Perform rating and lowered his price target to $33 form $35 on Restoration Hardware shares.
