Stock Selection Framework -King Stocks

 Let's break down your approach into three clear parts for easier understanding and implementation:

---

1. Stock Selection Strategy

• Choose stocks near all-time high or 52-week high.

• Follow the Bamboo Shoot Philosophy: look for stocks consolidating quietly then breaking out with volume.

• Identify strong technical patterns like cup and handle or ascending triangles signaling bullish continuation.

• Ensure solid fundamentals:

  • Consistent quarter-on-quarter and year-on-year sales growth.

  • Regular quarterly profits with improving margins.

  • High and stable promoter holdings (preferably above 50%).

  • Low debt levels.

  • Leadership or emerging leadership in their sector.

2. Investment / Entry Strategy

• Enter with 25% of total planned investment at confirmed breakout.

• Add another 25% allocation if price grows 4–7% above breakout and volume supports strength.

• Avoid investing full capital at once; scale in gradually.

• Set a stop-loss about 5–8% below breakout price to limit downside.

3. Holding and Exit Strategy

• Hold for the long term, targeting multi-bagger growth over 3-5 years or more.

• Be patient despite short-term volatility, if fundamentals remain strong.

• Book partial profits at significant milestones (e.g., every 50% gain).

• Use trailing stop-losses (15-20%) below peak price to protect gains yet allow growth.

• Review fundamentals quarterly; consider exit if growth falters, promoters reduce stake, or valuations become overstretched.

• Monitor sector health; reassess if sector weakens structurally.

Cheatsheet for choosing the right algorithm for string problems

 

Here's a cheatsheet for choosing the right algorithm for string problems, focusing on the most asked interview string problems in Microsoft interviews:

Problem	Algorithm	Time Complexity	Space Complexity
Longest Substring Without Repeating Characters	Sliding Window	O(n)	O(min(n, m))
Longest Palindromic Substring	Dynamic Programming	O(n^2)	O(n^2)
Anagram Detection	Hashing	O(n)	O(n)
String Compression	Run-Length Encoding	O(n)	O(n)
KMP Algorithm	KMP	O(n + m)	O(m)
Rabin-Karp Algorithm	Rabin-Karp	O(n + m)	O(1)
Find Duplicate Characters	Hashing	O(n)	O(n)
First Non-Repeating Character	Hashing	O(n)	O(n)
Reverse a String	Two Pointers	O(n)	O(1)
Palindrome Check	Two Pointers	O(n)	O(1)

Here's a brief explanation of each algorithm:

Sliding Window: Useful for substring problems, especially with contiguous sequences.
Dynamic Programming: Suitable for problems with overlapping subproblems or optimal substructure.
Hashing: Effective for fast lookup or counting.
KMP Algorithm: Efficient for pattern matching in strings.
Rabin-Karp Algorithm: Uses hashing for pattern matching.
Two Pointers: Useful for comparing or manipulating two strings.

This cheatsheet should help you quickly recall the most suitable algorithm for common string problems in Microsoft interviews.
