玩股撇步(動畫小學堂)  

  • 收帳和銷貨天數如果一直上升, 就要當心了!
  • 存貨在不同時期有不同的意義, 像是滯銷, 或是因為報價回升而屯貨, 或是積極備料, 這都需要去看存貨細項和判斷當時的情況來分辨
  • 當存貨增加時, 還需要注意增加的是不是商品或製成品. 如果是在製品或原物料, 反而有可能是供給不順沒法變製成品又或者是需求旺盛(短期營收趨勢向上)
  • 處在景氣下行的公司當存貨細項-原料和在製品的回升可能代表訂單開始回溫了
  • 當記憶體模組廠, 像是威剛、十銓存貨增加時, 有可能是在增加低價庫存, 代表著景氣循環來到相對低點, 也許就是建立部位的好時機
  • 當存貨提列減損損失,虧損認列在該年度,但是存貨價格回升後,之後年度也會直接回沖增加EPS,這種情況很容易在記憶體模組廠見到
  • 存貨一直增加,但是存貨銷售比沒什麼改變,可以推測是公司因為銷售良好而準備的存貨
  • 當淨營業週期(日)接近於0, 代表公司好像在做無本生意
