While we believe the market does anticipate comps below peer HD, we think the 200bp magnitude, reduction of buyback, and lowering of guidance is not fully in the stock which has only underperformed HD by 300bp ytd.” Cantor Fitzgerald reiterates Tesla as overweight Cantor said it sees a slew of positive catalysts in the months ahead for Tesla. “With shares currently trading at ~$350, we remain bullish ahead of several material near-term potential catalysts.”
