Recent Cost Distribution Last updated: 2026-03-25 (ET)

This reading is based on the last 20 trading days of 15-minute price, volume, and VWAP data. Price is trading 2.8% above the recent estimated cost basis of 175.32, which keeps the recent cost structure in a clearly stronger position. Price is in the upper half of the main cost band (175.50 to 181.30), which is usually a healthier short-term location because price is holding the stronger side of recent trading activity. The lower down support area sits around 170.72 to 173.79, and it still looks fairly solid. About 83% of recent positioning is in profit, which is a strong backdrop, but it also means momentum needs to stay healthy to avoid profit-taking pressure. From a trading point of view, the trend still has support, but because the main support sits lower down around 170.72 to 173.79, the key is whether pullbacks remain controlled before dropping back into that zone.

Why Price Reactions May Be Stronger?

Note: Short interest data is reported every two weeks by FINRA. The most recent snapshot is 2026-02-27 (ET).
