Few months back I have posted my journey towards AWS Certified Solution Architect – Associate exam. The link can be found below,   http://ahirjoy.blogspot.com/2022/06/how-i-passed-aws-certified-architect.html   However, while my cloud journey was going on well, there was a rude shock when I realized that my account got hacked. Though I was on long leave last month, I observed that my billing was increasing exponentially everyday though I was sure that I did not have any services running. Still I logged in to my AWS account to verify the same as I started getting unusual usage alert from AWS support also by then. To my surprise, I found many EC2 instances, VPCs and policies were created for my account which were very much active! Also, I found one subscription NVIDIA GPU Optimized AMI was subscribed for me in AWS marketplace!!!   I got panicked. I Immediately closed the account. However, to my disappointment I received communication from AWS support that unless the account...

Young professionals who belong to early Gen-Z (Born  mid 1990s) are voracious consumers of information and keep themselves updated with latest developments in technical and financial world. However paying too much attention to noise can sometimes backfire as they are just starters in their investment journey. Below are the various ways many early Gen Z investors are going wrong, 1.Over Enthusiasm About Buzz Words Like AI, ML, Quant: Whether it’s a new start-up stock advisory service or a big MF house, everyone is alluring customers claiming their state-of-the-art Artificial Intelligence or Machine learning or Quant model will generate superior returns, However these institutions are comfortably ignoring the importance of study of the fundamentals or impact of their huge fees/brokerages which will reduce the investor returns drastically even if the portfolio makes decent gains. Gen Z thinking AI/ML is the new magic wand of investment world, easily falling trapped here. 2.Over exposu...

Based on my experience in F&O trading here is a small write-up prepared for beginners in F&O trading, hope beginner F&O traders find this useful. Never go for naked options, it is the riskiest strategy. Even if you are almost certain about movement based on some news/events, you can never predict market. Always have a strategy in place and follow a strict profit target or Stop Loss for exit. I prefer spread based strategies – Bull Put Spread, Bear Call Spread, Bull Call Spread, Bear put Spread, The Iron Corridor etc which will help you to estimate potential risk-reward ratio even before you start! Never use your entire capital in one single trade, you may lose everything. Many small profits are always safer and achievable than one-time wonders which can cost you heavily if market moves other way. Read a lot, learn as much as possible. I will recommend the following books/courses for the beginners, i.   E-Book/Kindle - Options Trading...

Now most of the new investors in the market looking for good return over long run are not afraid to invest in equities, specially through Mutual Fund route. However most of these mutual fund investments are through third party brokerage houses of banks like ICICI, KOTAK, HDFC etc. When investors are investing in mutual funds through these route basically they are investing in “Regular Plans” of the fund houses. These Regular Plans attract extra charges due to various reasons like Distributor/agent commission etc.. Unknowingly retail investors are paying these charges which is making dent in their investments over long run. For e.g. expense ratio for Franklin India Prima Fund - Regular is 2.08% but the expense ratio is only 0.90% for the direct variation. The difference may be even more for other funds, you can try out with your own funds. Few years back after SEBI’s instruction, all mutual fund houses had to launch “Direct Plans” for each of their funds. These direct ...
