ACMR vs RUN

ACMR's Piotroski F-Score of 2/9 indicates severe financial distress, with weak operational and profitability health. The Altman Z-Score is unavailable, but the company's negative earnings growth (-77.7% YoY) and declining EPS trend signal deteriorating fundamentals. Despite a strong gross margin (44.39%) and low debt/equity (0.15), the sharp drop in earnings and poor recent earnings surprises (average -20.81% over last 4 quarters) undermine confidence. The stock trades at a premium to its Graham Number ($26.23) and intrinsic value ($9.59), suggesting overvaluation relative to conservative metrics. Insider selling of $16.59M in the last 6 months further reinforces bearish sentiment.

Sunrun Inc. exhibits severe financial instability, highlighted by a weak Piotroski F-Score of 2/9 and a high Debt/Equity ratio of 2.98. While the stock trades below its Graham Number ($22.71) and Book Value (P/B 0.92), these value metrics are offset by negative ROE (-22.06%) and a bearish technical trend. Massive revenue growth (123.5%) is currently decoupled from consistent profitability, and aggressive insider selling by the CEO, CFO, and President signals a lack of internal confidence.
