The JSE stock traded at an outlandish $13.50 & dropped 47% since.

It is not nice to watch one’s investment lose value while others grow delivering big gains at the same time. Many investors plunge into investments that will result in just that happening, as they err and refuse to let go and reinvest, to recover their loss, from gains elsewhere.
A look back at prices in 2005, reveals shocking results of costly ill-timed investments. In June 2005, investors in a bout of excess exuberance, pushed Mayberry Investments to $8.40 from a listed price of $5.05, weeks after it listed on the Jamaica Stock Exchange, 12 years later it is still to reach back to that level. That is a huge blow to investors who held on to the shares from then.
The sad thing is that many investors who wanted to sell could not, as attempts were made to control the price from a big drop as selling started to overwhelm buying a few days after nearly 40 million shares were traded around the $7-8 level. Mayberry is an outstanding example of investors making huge errors based on inadequate information and paying dearly for it.
But Mayberry’s stock is not the only one that investors underwent a long period of suffering from, they have a number of top notch companies as their friends that that performed poorly until fairly recently. Scotia Group was pushed to $33.50 in March 2005 based on results that were not sustainable as the bank benefited by a poor decision of the Central Bank to push interest rates on CDS paying interest at elevated levels for about two to three years. The banks of course made a killing when rates fell back. Added to that, Scotia effected a stock split that sent the stock flying. Well it was not until late 2016 that the price exceeded the 2005 high. JMMB Group’s shareholders saw the price of the stock peaking at $22 in April 2004 only to see it fall away and not getting back to that level until recently this year. That is not great for a stock that is not a great dividend payer.
Grace Kennedy hit a high of $123 (Now $41 after stock split in 2016), in January 2005, it has taken nearly 12 years to recover the loss and it has still not delivered much more in gains since its full recovery.
Markets tend to repeat past behaviors, over and over but sometimes they take a break from the norm. PE ratios are the end product of investors’ perception of values for stocks. There are other measures but the PE is the most widely used. When PEs are pushed well beyond where the majority of investors thing the value ought to be, they induce added buying or selling. Investors who buy when the market has pushed valuation well above what is considered the norm, usually pay a steep price for so doing. The 2005 examples are cases in point. An accepted concept is that the PE ratio should be line with profit growth. One year’s growth cannot be used by itself but investors have to try and determine that themselves.
Most of the stocks in the IC Insider’s Exuberant 10, were pushed in 2017 by excessive enthusiasm and in some cases wrong information. Stock splits helped to fuel some of the excess as well. The attached table shows the stocks that were pushed well above their appropriate values and the levels of correction since. Some may fall even more than their latest price as they can be considered overvalued based on known earnings for the current period. A few that are not on the list could see a decent fall as well, included in this latter list are Knutsford Express and Kingston Properties.
