Long-term investment approaches.

I just read and interesting approach to regular investments/savings, to my surprise it came from financial adviser...
Until now, I've known few approaches:
- invest same amount of money every month
- buy same amount of mutual fund units (or stocks) every month
- keep the coefficient of investments in safe/unsafe instruments at a constant (B. Graham)
- progressive investing using futures (gaost.pl - currently down)

Today I read about another approach - buy that amount, which will keep your investment growing at desired level (i.e. buy $1k every month - if you lost $600 - buy for $1600, you gained $300 - buy only for $700). Interesting. Perhaps can be combined with 3rd approach for greater efficiency.

Somebody predicted...

...mortgage meltdown. Well, maybe not in full, but anyway this is an impressive read:

Last week's red color was pretty depressing. On the other hand, I'm pretty sure, that this is really close to the bottom. At least Poland's position is really strong. I think we can highly benefit from this crisis, as our banks are healthy, mortgages are still small percent of the GDP, and GDP itself is still growing quite fast. Inflation should not be that much of an issue with dropping food and gas prices as well. The core thing is to leverage our lower costs in export. If we can do that, and sell our stuff and services to now-frugal western Europe we can do really well, and close the gap even faster than in good times. Oh - and I forgot - amount of outsourcing placed in Poland should further increase, I hope.
