What is the feasibility of the various Governments engaging in 'stock buying operations' to support various stock markets, WITHOUT SUCH OPERATIONS BEING ANNOUNCED TO THE GENERAL PUBLIC? It is easy to see how various policy leaders might justify this, to maintain confidence in the markets etc. until 'normality' returns. If we didn't know about such buying then any underlying market strength/resilience might be perceived as due to real end user demand thereby encouraging others to buy (trend followers etc). Clearly such measures would be financed using taxpayers money and there is the small matter of 'accountability' so is it realistic to believe that this could be done on a large scale without any announcement? No doubt policy makers would contend/believe that they are acting in everyone's 'best interests', I am just curious as to the feasibility of a plan without any announcement... Any thoughts?? Thanks in advance for any feedback.
