In my case I hold a specific share to get the high dividend. In between ex dividend dates I also trade the share. I only take my profits out of my account.
So I open an account with €60k and purchase my share. I then trade this share 6 times throughout the year. Basically leaving a hard core €60k in my account. What are my charges likely to be.
Assuming this is a single UK/Irish share and ignoring profits and stamp duty for the minute, then -
With a Davy Select Trading Account you would pay €80 per annum maintenance charge, then €300 on each transaction (0.5% of €60k). Not sure how many buy/sell transactions you mean by "trade 6 times" but assuming you buy in once, then sell/buy/sell/buy/sell/buy then you're looking at seven transactions, so total cost for the year of €2180.
With a Davy Select Plus Trading Account (the 0.9% model account) you would pay €540 per year, half in June half in December.
Also worth considering other option as I don't think Davy is the cheapest way to do this.
Using the example above, DeGiro would cost you €182 in fees per year.
Or have you considered spreadbetting this share instead? If you do it with no margin/leverage then you're getting the same exposure to the market risk/reward wise, but you pay no tax on the gains or dividends. ayondo for example have no annual fees or transaction fees, they make all their money by slightly inflating the bid/ask spread, which seems to be very small (I'd suggest signing up for a demo account and having a look at the share you're interested in, see what the spread looks like) and would be blown away by the saving made by not having to pay tax. One thing to note is that these spreadbetting companies are not as highly regulated as your Cantor/Davy/DeGiro though, so there is certainly additional risk assumed in this way.
