I wouldn't read too much into the sell in the last two days.
If someone with a larger holding needs to liquidate their DTS holdings or believes in other opportunities and sells there holdings it will have a temporary negative impact on price.
I agree with MrSiliconValley when most of the shares are held by 30 or so shareholders it makes it difficult to buy or sell 500.000 shares or more without having an impact on price.
The business is appearing to progress nicely and the appendix 4C quarterly report should give everyone the confirmation. The 4C is due by the end of the month but hopefully released earlier and hopefully released with general company developments.
