I mentioned in a few earlier replies to individuals requests for some ideas on how I would invest a specific amount of money, the 2 instances posed were $3,000 and $12,000. Some might just think just invest them both the same with the $12K one being 4 times the total invested in each stock, but the different amounts of money means different things should be taken to mind. Before i go on more i wont go into specific stocks you should buy into as i am not going to take responsibility for potential losses if following my picks, though at a later point i might re adjust this attitude and provide specific stocks to pick. But that is not now so i will keep it general. Also remember once you choose a stock the work is not over, the general rule of thumb is for each stock you own you should spend 1 hour a week researching it to make sure it still holds true to the reasons for investing in it in the first place.
The first thing to take to mind is what your goals with investing are, either capital growth or capital security. With the $3,000 investment i would look to break the investment into 4 differing stocks, this could be an even 4 way split of $750 or lopsided for a specific stock you feel will provide the best growth, or a more Conservative strategy with the larger portion going into a Large Cap company with a secure dividend. The reason i wouldn't go more then 4 individual stocks is because of the amount of the investment it would not be wise to overload on to many stocks to keep track of and monitor the health of the company. Remember to make sure you are not weighted to much to an individual sector of the market, by sector i mean you shouldn't have all 4 stocks all be Technology companies. I also recommend one of the stocks you choose to be a secure investment with a good secure dividend.
With the $12,000 scenario you have more flexibility with your choices and can be flexible with reacting to changes in the market. I would take a similar approach as the strategy mentioned above, but use $9,000 invested between 8 and 10 stocks. With this you can invest in multiple stocks into the same sector, but i would stay away from putting more then 30% of this investment money into a single sector. Now with the remaining $3,000 is the flexibility of having a larger bank roll comes into play. I would take $1,500 of this money and invest it in 1 or 2 speculative stocks, these would be stocks that have the potential to become huge movers in the near future, but they also have a larger risk attached to them so be careful. The remaining $1,500 i would suggest keep in reserve in the account for instances when market factors make it worth wild to make a quick buy into a stock at a low rate after a sharp sell off or when you wish to double up on a previous investment, or even open a new investment that would have otherwise forced you to sell off one of your other investments to purchase it.
Good luck guys i would love to hear some feedback from the simulators.
