COST was over-speculated by retail groups. Extreme angles of ascent do not hold. The severity of the recent angle of ascent due to speculation warned well ahead of time that COST would have a meltdown when buyers evaporated. The first strong support level is at the black line.

The Weekly chart shows stronger runs up than down. Costco is frequently speculated as there are retail gurus and chatroom groups, etc. that run the stock up from time to time. However, this stock is absurdly overpriced at this level and needs to do a split.
