Rule-based technical strategies computed from this stock’s own price history only. Signals use only data available through the prior trading day (no look-ahead), and trading costs, slippage and taxes aren’t modeled. A backtested rule performing well in the past is not a guarantee of future results — this is an educational illustration, not investment advice.

Composite of 3 factors below, ranked against the 3752 U.S. stocks BeStock covers.

12 analysts, consensus Buy.
How this is scored: each factor above is a 0–100 percentile rank against every other stock BeStock covers (or, for Wall Street, against the five-point Strong Buy–Sell scale). The overall grade is the plain average of whichever factors apply to this stock — no factor is weighted more than another. That average maps to a letter: A ≥ 85, B ≥ 70, C ≥ 50, D ≥ 30, otherwise F. Recomputed from the data on this page as prices and filings update — it describes where a stock ranks today, not a forecast, and not a BeStock recommendation to buy or sell.

Backtested performance, updated weekly — not a guarantee of future results, and not a BeStock recommendation.
What Wall Street analysts and Morningstar's fair-value model expect for the stock
Wall Street’s average 12-month target is $28.18, 77.9% above today’s price, with a consensus rating of Buy.

On earnings multiple, it sits in the 30th percentile of its own five-year valuation range (cheaper than usual).
Figures are Wall Street analyst consensus and Morningstar’s independent fair-value model, sourced as noted above.
