^Sis, i suggest you read a book about investing first.
For instance..
https://marvingermo.com/books/or attend trader's lounge PH.
Kasi mapapaso ka if you will buy shares of certain stock without any goals or plans. The stock you might think is a good investment, pwedeng bumaba pa ng bumaba, doon ka mapapaso.
Stock investing sounds good and promising pero pag wala tayo alam sa fundamentals and technical analysis, pwedeng one wrong move, bagsak ang investment natin.
Learn about support and resistance para maestablish mo when to buy and when to sell. This will also help you cutloss (magbenta ng palugi) pag hindi na akma sa plano natin ang isang stock.
Points to think about:
1. Learn to avoid asking what stocks to buy - kasi some people will hype a particular stock (they will tell you buy this - palugi pla yung stock), then once it has reached a lot of buyers at tumaas ang price, magbebenta sha leaving you with that paluging stock at an expensive price - eto yung hyping, they make a particular look good para lumaki ang demand and makapag sell sha at a given price.
2. Ask your self what is your goal - pang retirement ba (10 years or more) or pang wedding (short term)? in this way, maplan out mo kung ano ang stock ang maganda for your particular need.
3. Study support and resistance, plot excel sheet for your analysis and consult Trader's lounge PH sa FB.
4. Take a look at your emotions, hindi pwede emotions ang mag dedecide kung ano bibilhin mong stock kasi once bumaba nag price ng saglit, you need to ensure you are emotionally prepared kung mag negative ang portfolio mo.
5. Build a foundation like emergency fund (monthly salary x

, life insurance, hospital insurance, etc. This will ensure na kahit matalo ka sa stock market, hindi affected ang mga monthly expenses mo. This will help you sleep soundly at night. and take note: Ensure that the money you will use are extra money na pang "gamble" mo.
6. If you are already knowledgeable, 8k php ang rule para macover ang commission ng brokers, taxes, etc. Meaning, if you invest less than 5k, kelangan mo ibenta ang shares mo at a higher price para makabawi ka sa mga additional fees.
7. Invest in index fund if you want to avoid any "tutok" sa stocks. What I do is I invest if PSEI is mga 6k ish or below.
8. If you can, fund your online broker ng any extra money you have everymonth. Establish a schedule buy of a particular stock or index fund para kahit di mo icheck si COL, nakakabili ka ng stock on its prevailing price. It will accumulate and over time, pwede mo na ibenta ang na accumulate mong shares.
Good luck.
