This is a deliberate attempt to interfere with the free and fair operation of the market and create artificial, false or misleading appearances with respect to the price of a security.

Examples

1. Pools:
"Agreements, often written, among a group of traders to delegate authority to a single manager to trade in a specific stock for a specific period of time and then to share in the resulting profits or losses."

2. Churning:
"When a trader places both buy and sell orders at about the same price. The increase in activity is intended to attract additional investors, and increase the price.

3. Runs:
"When a group of traders create activity or rumors in order to drive the price of a security up."

4. Ramping:
"Actions designedto artificially raise the market price of listed securities and to give the impression of voluminous trading, in order to make a quick profit."

5. Wash trade:
"Selling and repurchasing the same or substantially the same security for the purpose of generating activity and increasing the price"

6. Bear raid:
"Attempting to push the price of a stock down by heavy selling or short selling."

How is it possible to being doing the two at the same time? Wouldn't it be better to try one thing at a time?

My observation is that the Kenyan market is far from efficient, it is until CMA gets serious with managing the market and strictly enforcing governance across companies.

It would not be a surprise to find that some senior managers have connections to trading houses.

My observation, lunch hour records the highest disparities

I wouldn't be surprised if CMA is part of the cartel. Its a sad state of affairs, man eat man market. Just some time back the price of dollars was artificially pushed up, for someone to make a killing at the expense of a whole country.

I've experienced front-running of orders severally even this yr. Its especially prevelant when the NSE iko down for a while.
