RE:RE:Trading B shares for A sharesWhat you are saying is correct but this is exactly what you want to keep trading back and forth between A and B shares. I have owned Bombardier shares for over 20 years. 99.999% of the time, A shares are more expensive than B shares and B shares are in the driver seat meaning that A shares are totally dependant of B share prices. Lastly A shares are always dragging behind B shares because of their low volume.
However, most of the timeI A shares were 10 to 15 cents (pre reverse split prices) higher than B shares. Occasionally it was only a few cents higher (pre RS) than B shares but at other times I have seen $1.0+ (pre RS) higher than B shares. My trading is done when A share prices are either very low or very high when compared to B share prices.
Hence my approach was selling B shares and use revenues to buy A shares at a slightly higher price and selling A shares to buy back B shares when A share prices were much higher than B shares.
Just for the fun of it, do a little bit of maths and see how much you can increase the number of shares in your porfolio everytime you do complete a full cycle.
Now that we are post RS, I usually sell some B shares to buy A shares when the price is less than $1 above B (4cents pre RS) and reverse the process by selling A shares to buy back B shares when the price difference is $3 to $4.
Check your old share prices data and you will see that these events happen occasionally and you need to capitalize on them. As an exemple, shortly after RS, there was $5 to $6 difference betwen A and B share prices. That was the perfect time to sell your A shares to buy some Bs.
